EV charge times

I have an EV and a Zappi. The Zappi can work in different modes, eco, boost, scheduled. In the Eco modes, it will only charge the car when there is excess power from solar panels, and will stop charging if other appliances start to draw power. The eco modes can be set to allow some mains current to top up the solar panel current to a minimum value.

Boost mode allows for a full 7kW charge on demand. Scheduling enables the charging time to be set to correspond with off peak tariff times. I find that this is used more in the winter when there is less input for the solar panels and when we need a full charge before a long trip.

The Zappi installation consists of 3 elements, a hub which feeds back data to the Myenegi app and web site and enables downloads of software and firmware upgrades. There is a Harvi which connects to CTs in the consumer unit to monitor grid current in/out, solar panel current in. This information is fed to the hub. The app provides a lot of useful information about power distribution to the car, the house, in/out the grid, solar panels.  There is also another unit which can be added if you have a storage battery installed.

I am currently on the Octopus Go Tariff which provides 4 hours per night cheap rate, 5p per unit.  I am closely monitoring the energy consumption distribution to understand the true cost of charging the car.

I have no connection with MyEnergi or any installers.
